The Mysteries of the Universe Beyond Our Reach

Introduction

• Vast universe: trillions of galaxies, billions of stars
• Space exploration: our tool to understand existence, push knowledge boundaries
• Historical perspective: from naked-eye observations to modern space probes
• Continual surprises and learning in the 21st century
• Each discovery contributes to understanding our place in the cosmos

Groundbreaking Space Discoveries (21st Century)

1. Water on Mars (2015)

   • Detected by NASA's Mars Reconnaissance Orbiter
   • Liquid brine on Martian mountains
   • Potential for life: microscopic organisms

2. Discovery of Exoplanets

   • Kepler Space Telescope's role
   • Transit method: planet's passage dims star's light
   • Over 4,000 exoplanets found
   • Implications: Solar system not unique; potential habitable worlds

3. Dark Matter

   • Unseen substance, 85% of all matter
   • Influences galaxy motion
   • Key role in galaxy formation and universe's expansion

4. Gravitational Waves (2016)

   • Detected by LIGO
   • Generated by astronomical collisions
   • Validated Einstein's predictions
   • New method to observe universe

5. Higgs Boson (2012)

   • Detected at CERN's Large Hadron Collider
   • Explains why matter has mass
   • Interaction with Higgs field: particles acquire mass

6. TRAPPIST-1 Solar System

   • Discovered in 2016
   • 7 Earth-sized planets
   • Located in constellation Aquarius, 40 light years away
   • 3 planets in habitable zone

7. First Image of a Black Hole (2019)

   • Captured by Event Horizon Telescope
   • Supermassive black hole in galaxy M87
   • Confirmed Einstein's theory of general relativity

8. Organic Molecules on Mars (2018)

   • Discovered by Curiosity rover
   • Building blocks of life found in Gale Crater
   • Raises possibility of past or present life on Mars

9. Interstellar Object ‘Oumuamua (2017)

   • First known object from outside solar system
   • Unusual elongated shape
   • High speed and tumbling motion

10. Fast Radio Bursts (FRBs)

    • Intense, short radio waves
    • Origin still unknown
    • Energy release: equivalent to 80 years of Sun's output
    • Theories: neutron stars, extraterrestrials, cosmic explosions

Reflection and Future Outlook

• Water on Mars: future missions
• Exoplanets: hunt for Earth-like planets continues
• Dark Matter: ongoing research to understand its secrets
